Add some tests to validate dequeue blocking behavior when the IGBP is configured in async mode. We want to validate that in this mode, with or without blast, the client will not be blocked when dequeuing a buffer. Instead, when the client tries to queue a buffer, the bufferqueue will drop the queued buffer if it exists. In async mode, the bufferqueue in the will have an additional buffer so for blast: one buffer will be acquired and presented, one buffer will be acquired in the queue, and the client will have two buffers left for non blocking dequeue. When queuing a buffer, the BQ in the adapter will drop the last queued buffer if available. Test: atest BufferPresentationTests Bug: 176916466 Change-Id: I6ff45c24d6529cc7cd4169f962eb2ca9cbc09943
